How to fix Radio (3G) not working (voice calls, data)

[dauphinas365]

My original HTC (Radio 1.27.12.11) never was able to recieve or create voice calls via 3G nor do any data transfer. Only GSM mode was working, but then for what reason I was going for the Kaiser ?.

Thanks to Pof's work on the HardSPL tool and Dark Simpsons "htc rom tool" and all others contributed to this tools, using the posted french ROM with Radio 1.27.12.17 and the rest from the original HTC rom I compiled a new ROM image.
With this Radio rom I just confirmed that 3G is now working using voice and data. All former 3G problems are gone.

Steps:
- Downloaded original HTC rom and French rom
- Using "NBHextract.exe" to extract the rom components.
- Using the "00_unkonwn.nb" from the french and the rest from the original HTC rom and compile using "htc rom tool" a new rom.
- Now using HARD SPL to install new boot loader and then just transfer the new rom using the original HTC upgrade package with the new rom instead the original one.

can you post your rom ?

[dauphinas365]

Just replace the rom in the HTC_WWE rom-installer with this one. Worked for me without any problems with Kaiser got from UK, but no warrenty

[dauphinas365]

Looks like it was a bit too optimistic. Here are the results of 24h usage:

-3G voice and data are sometimes working. With the 1.27.12.11 it never worked with 1.27.12.17 it work for some calls / times and then 3G still looks like logged into the 3G-Network, but phone is unreachable. The phone needs to be switched off/on again to get it working. Then one call / data connection / incoming call is possible. After that darkness again. At least one 3G action is possible in comparion to earlier radio rom, but it is still far away from perfect.

It is an improvement but HTC has still to do a better job with the radio rom. Hope we will get an update soon behind 1.27.12.17

thanks, I'll give it a try in a few days.... as to warrenty - HTC appears not to honor warrenties, HTC US said "not our problem", HTC UK has not answered in over a week....

[dauphinas365]

... now I run for 24h with the french rom, no customization.
It is better then the HTC with the replaced Radio, posted above. I can call 3G, do data connections and receive incoming calls. It seems after 24h pretty stable. Therefore it looks like changing the radio is not enough and that as the french rom using a slightly newer OS then HTC original, there are some changes too included.
- Problem: Roaming between GSM and 3G, somtimes the phone needs 5 or more minutes to login into the network again after areas with no coverage. Completly different to the Nokia N95, which can handle such issues with no problem @ all
- About HTC service. I called them too and they tried to direct my to a service partner I should pay for getting my problems solved, that is very different to what I understand about warrenty too.

I would be really thankful for anyone who could produce a Radio-only flash available using the French .17 Firmware.

The stock .11 radio ROM is completely, I mean really completely useless for me. Any time I try to write a SMS, make a phone call or data connection my Kaiser immediately loses the connection to the network and I have wait for the phone to reconnect itself. I also cannot receive any incoming calls.

I remember that the first radio ROMs for the Hermes were terrible but this is even worse. Too bad because I'm really enjoying the rest of my Kaiser so far.

[dauphinas365]

I have done lots of test and added above a rom HTC with french .17 radio stack. But there is more then then just the radio. It is better with the mixed rom, but still not good to use it as a reliable phone.
Best what you can do is using the french rom and you get a 50% chance that 3G works incoming and outgoing.

[vacsed]

I'm rather new to creating my own cooked ROMs so I'm right to think if I want to upgrade my Kaiser to the .17 Radio ROM, the only thing I need to do is create a .nbh file from "02_Unknown.nb" and flash the resulting nbh file using CustomRUU and my Kaiser will not be completed formated?

I'm asking this because my Kaiser is now perfectly configurated and personalized and I don't want restart install all my programs, I just want to try the new Radio ROM because the current version is completely useless.

Thanks for any info

[vacsed]

well disregard my previous post, I just successfully flashed my Kaiser with the new Radio ROM and hopefully I will actually be able to call someone with my PDA phone.

[hanza]

Hi all, first I have to say that I'm in Dublin Ireland using vodafone and have my kaiser for about 3 weeks now and the most odd thing about that would be that it has been working fine 3G and 3.5G when within good coverage. All of a sudden last sunday it just stopped working with 3G I believe that network provider just changed something with its settings but I can't be sure. I would love to see a radio update soon but since I don't believe in miracles I've been trying some temporary workaround just to be able to call and text. It seems that it enough to go to settings -> phone -> network and set the BAND TO GSM. This way it doesn't use 3G but at least I can use the phone. Hope it could help anyone there.

[vacsed]

Thanks for the info, I'll try that eventhough the .17 Radio Update did improve network connection somewhat but it's still subpar.

FYI, I was last Saturday in Dublin, eventhough only for an hour, and of course I tried my Kaiser but the 3G data connection completely refused to work. This was when I still had my .11 Radio ROM installed.

So far I have tried my Kaiser in London, Malpensa, Madrid and Berlin so the issue seems to be rather ROM related than provider related.

[hanza]

you're right, it has nothing to do with the provider I was wrong. I took my card from Era Poland with roaming and turned on my Kaiser. On O2 I had two bars on HSDPA and that beautiful H letter on the top of the screen but not possible to make a call, send sms or whatever. Switching to gsm always works. I upgraded to .17 and it looks exactly the same as it was I see no difference at all. The only thing that bothers me at the moment is that for me it's been working fine for some time. I've been using 3g in Dublin and Warsaw as well and for some reason it just stopped :( I just hope it's not any hardware issue.

[decimusmaximus7]

Is this rom posted on #1 a radio only or the whole thing?

[maffe]

I have the same problem over here. I have the Tytn2 for one month now. I had vacation and i took the plane at Amsterdam (Schiphol) to Tenerife.
When i arrived in Tenerife i get a 3G icon and cannot make calls and cannot internet. I had manually switch to GSM band. Now back in Holland with auto-settings i have the same problem again. With 3G i can do nothing (call/internet). Anyone any idea?
I have a vodafona abbo, my simcard in the old tytn1 with same settings works well at 3G. Soon i call with htc!

[zippert]

Same problem here with HTC Tytn II in Holland on T-mobile,
switched 3G to GSM and luckely I can use the phone now,
but I really hope there will be a fix soon!

Thanks!

[scwilson8382]

I'm having the same problem with my tilt. I had the 3G before the flash but have not had it since.

[martyotaku]

same her in nyc ...tried both radios....3g doesnt work....help....please:(

[maffe]

A hard reset does NOT fix the 3G call/internet problem
When i switch the telephoneband from auto to GSM the phone get's connected at G and i can call. But i want videocall.
Please someone ? Defect or waiting for rom ?

[millercentral]

I too am experiencing this problem. It happened overnight one night -- 3G will not connect -- neither voice or data, but GSM (edge) works fine.

I'm on ATT, HardSPL with Schaps 4.22 rom. It was working fine in this configuration, then suddenly stopped. Tried Hard reset (no help), and tried upgrading the radio to .17 (also no help). Next step is to try and revert to original ROM/Radio/Bootloader (per "how to restore to factory for rma thread") to see if that helps.

If anyone comes up with a solution, I'd be grateful.

[JoBi]

Hi,

since 2 weeks i have the HTC Kaiser too and i am sure that in the beginning the 3G worked fine.

Since a few days i cannot make or receive calls and i am not able to use the Web during i am in the 3G-mode (set to auto).
First I thought it would be a Network Provider Problem but the same happened to me with another Provider too.

Anyone can help me???

Thanks in Advance!

[slwoon]

Hi there,

I had exactly the same problem with you since day 1 I bought HTC TytnII. I have tried many things including changing to various roms and radios but no success. I finally sent the unit to HTC service centre to have it fix. The engineer there did not tell me exactly what went wrong but they said they are going to change the motherboard. I have not get the unit back yet so I cannot tell you whether they have fixed the problem.
My suggestion is you should send the unit to HTC for them to have a look.

[richied]

hi,

please see my other posts, exactly the same problem. Strange thing is some areas will work with 3G others won't. It worked perfectly for about a week when I first got the phone too. AT&T does seem interested, they have called me and said they are investigating a number of complaints like mine. will try a new phone when they arrive at the store where I got it. the mother board swap a previous poster mentioned is disturbing though...now will we have to track hardware revisions ..arrgghh!:-)

[maxloser]

Dear All,

thanks for your contributions all over the world. It happend to me in the same way in Germany. 1 week it was ok. After that no chance to make a call over the 3G Network (Simyo/e-plus). If somebody exactly knows if it is a hardware problem the service of HTC will have some work to do!! :cool:

[bmueller77]

@all: Do not use the Connection Wizard to set up your connections. I had the same problem with every Radio Rom but after doing a hard reset and NOT using the Connection wizard, all my 3G problems are gone.
I first thought, it was the new SimCard, but it worked on another phone and a SIMCard from another provider worked on mine. After ignoring the connection setup wizard all works fine for three days now.

Please tell me if it worked for you as well so i could add it to the FAQ.

[richied]

Hi,

what do you mean not to use the connection wizard....what did you do then..how did you set up usernames and password etc? Please elaborate?

thanks

i set the connection manually as in the time before the connection wizard ^^

bmueller77,

thanks, I thought maybe that procedure was the wizard you referred to. We maybe don't have a wizard app on AT&T that you may have on your provider then, as that procedure you referenced is the only way I know of to setup my connections. Oh well....back to the drawing board.

thanks anyways!

The procedure is the same at the Kaiser cause it is the same operating system ^^. And the settings themselves are for the network, not the device.
There are just old descriptions on how to set up these manually, because everyone uses the connection wizard. I could write you a new description made for the Kaiser. But it would be the same like the one for the wizard.

Thanks a lot for your Post, but that doesnt fit to our Problem because in your linked Thread is only described how to setup the data connections for wap, web and mms.

Our Problem is that our beloved Kaiser isn´t able to work in 3G (UMTS)-Mode and the only Way to choose the Frequency is over start-control-personal and there "telephone" where you can choose between the "old" GSM or 3G (UMTS).

I talked today with my seller again and he said that i have to sent it to www.brightpoint.de for guarantee-repair.

Did you try it?
I don't know what the Connection wizard sets, that causes this error, but when i configured my MMS and GPRS/UMTS manually, the problem did not occur anymore. 3G worked without changing something to the standard 3G/GSM-settings.

Try the following before sending your device away: hard reset, then dismiss the connection wizard when it comes up and deactivate it. Then try to do a call with 3G. If it works, run the connection wizard and i'd bet, after running it, your 3G problem will occur again.

[JoBi]

....Try and Error ;-)

Of course, since nearly one Week i try really everything i can to fix that Problem, but your described way doesnt works for me and let me say it again, I think it cannot work because the Connection Manager only is setting up your WAP, WEB and MMS-Connections but never your Frequency.

But thanks a lot for your answer of course!!!

Anyone with another hint without flashing the brand new Kaiser???

;-)

[croje]

I'm having a bit of a different issue with 3G I think. UMTS/HSDPA internet works, and I can make calls, except that most of the time I can't be reached even though there is bars on the reception thingy. This only seems to be when the phone is standby.

And then, when I make a call, all of the text messages and missing calls come dripping in. Is this somehow related to the issues you guys are describing?
Or could it just be bad reception?

thanks

Hi,

i tried to follow the description of bmueller77. I made a hard reset and reloaded all the original Vodafone Roms. I could not succed. It might be that
I have to change the ROM? But I like to b 100% sure that is no hardware Prob. But I can see the 3G symbol and if I try to make a data connection e-plus refuse or I can't make a call over the 3G Network.

What a pitty :mad:

Maybe there is someone who has bought an German Vodafone with the same Prob.

.... I am sure, its not a Problem of the Network Provider, because i tried it with my T-Mobile and with the Vodafone SIM with the same error.

By the way, every time I wake up my Kaiser from the Stand-by-Mode i can see full coverage in the status bar and only seconds later there is nearly no coverage in 3G-Mode.


Today i have send my Kaiser to www.brightpoint.de


Have a nice weekend!

thanks, do keep us posted, I am waiting for new units to arrive to swap mine..but am skeptical this will fix anything.

bmueller77,

one question on your fix, by chance did you try it in the same area where 3G previously failed? I ask this because I thought I had a fix( that didn't make sense) but later found out that in some areas I can operate in 3G but in others I can't. Of course I tried it in a working area and assumed I had found a way around the bug erroneously.

thanks

I think and hope its the same procedure like here:

At first you need a network provider who sells this service and here in Germany you need a newer SIM-Card called U-SIM (with the ability to serve UMTS)....that quiet all

Tan you must choose in your Kaiser under start->control->personal the "Telephone Icon" and there go to the ..hm..its called "BAND" here in Germany and choose the 3G/UMTS or how is it called in the USA???

Hi Thanks for this advice, I'll try your suggestion and let you know... I've just upgraded to the same ROM, Radio as you have to make sure I have the same conditions... my Kaiser just returend after 6.5 weeks at HTC repair center and they haven't done anything on the device!!! Nothing!!! and have exactly the same problem as you all are describing here :-( So this is my last try before getting really "*%"!** :-(

I'll keep you posted, as I also need to try on several locations for several days before having the problem showing up after a hard reset...

Thanks anyway.

[XzaniX]

OK... sorry, doesn't help on my Kaiser, after upgrading to the same ROM&Radio, and skipping the Network Wizard, done setup manually... still the same f***ing behaviour... £G on signal OK, no call nor data possible... OK, I have to fight for a refund. Thanks anyway.

Well, i tried to do calls from home and at work and it never worked until i performed the steps described before. Maybe some (maybe all of you) have another issue, but this worked for me and i am using automatic 2G/3G-mode regulary now without any problems.
As i said, i cannot say what additionally setting is set by the wizard that caused the issue to my device. As described before it should not affect the GSM-settings. Just the developer may know...

Maybe my way helps some of you. If not i hope you'll find a fix for your issue soon.

[Ves]

I had the same problem. Send my TyTn II to repair and got it back (on the 2nd attempt) with a far better 3G receiving. Seems the chips regulating this is weaker on some phones then on others and on some even breaks down.

My advice send it to repairs, and keep sending it untill they a. fix the chip (read. replace the board) b. send you a new phone.

I am on T-Mobile Hungary and just been back to a European and African trip visited several mobile networks. Sad thing is my 3G is gone. I realized it in Brussels but when I got back to Hungary It did not work here either.

I did the Hard Reset and skipped the Connection Wizzard but the problem still exists.

What is the solution? Do we need to send back each and every Kaiser to the factory? Something is really wrong if you take it abroad!!! :mad:

How long does it take to get it back from the factory?

Funny, this problem started with my Tytn II a few days after retuning to Germany after a trip to the US (Florida, Orlando area). But only after i started flashing again (from Dutty's No.7b to v3)

[belmont007]

I have the original ROM burned by HTC and seems it does not really depends on the ROM versions. Seems we have a hardware issue on some radios. Another strange behavior is when I set band to AUTO it so often changing between 3G and EDGE even if I have full signal strength on 3G. This is abnormal.

[Brevi]

Ok, this is really weird:
I packed up my Tytn II today to send it in for repair. I put the Sim-card into my old hard-reset XDA Trion (aka Hermes aka Tytn) and it showed exactly the same behaviour!!
The Hermes worked perfectly till December, when I got my Kaiser.
I called O2 germany and they couldn't make sense of it either, as I already have the newest Sim-Card standard.
Will tell you as soon as i get more info.
I attached a photo of my new/old Sim-Card
BTW: Both are O2 Multicard's where you have up to three cards with the same number at the same time logged into the network and can choose via web or gsm codes, on which phone calls/sms/mms etc will arrive.

[richied]

Brevi,

your problem seems to correlate with mine somewhat. I don't have an older 3G device to test with by swapping the sim, but my old razer works fine with the tilt sim. Anyway, my 3G issue started when I traveled to NH once..probably causing it to roam. It (3G)hasn't worked again..EXCEPT for a 3G region in central MA...wondering if the bug involves the sim not switching or accepting parameters back to the home region once you roam out of it...just brainstorming a bit. I will be getting a replacement tilt today as I am within the 30 day window still. We'll see then. Is there any way to make a poll here to see how many people are having 3G problems does anyone know?

rich

[Brevi]

The issue with roaming got me thinking. I live in Aachen, Germany. It's very close to the border of Belgium, Holland and Luxemburg (the drei(three)-länder(countries)-eck(corner) so much for a lesson in german ;-) ). I sometimes drive to Belgium to get coffee (it's kinda cheap there and a nice short trip) I have been there before with my Tytn II, but not since the problems started. Also i can roam a few networks there, which I can't in Germany, where I am restricted to O2.
Will try in the next few days and let you know. Wish me luck.

edit: Oh I just tried some Vodafone Sim-cards i have flying around, cause i got a phone much cheaper with the contracts. UMTS calls in/out work perfectly with the Kaiser and also the Hermes!!! So i guess this definately is a network issue with my device. Called O2 and now will have to run some test calls tomorrow to report to them.
They just won't believe me, will they? ;-)

[richied]

Hi,

I just wanted to post an update, I replaced my tilt yesterday under the 30 day trial, also they swapped the sim card for another. I drove to 2 different 3G areas and it worked fine in 3G mode with the stock at&t rom. I spent last night reflashing back to Dutty's v7b and restoring my applications etc. I will drive to a 3G area today and verify it still works, edge is working fine here at home. Interesting note, the radio that was on the new device with the stock rom was 1.27.12.17...which I had changed to on my first tilt. Either AT&T updated to this rev..or possibly does the radio follow the sim card? Would the radio rev move to the new sim when they moved my contacts to it? Not sure how this is all managed.

rich

[richied]

I drove to a 3G area today while running google maps and it picked up and switched to hsdpa without a hitch. I made a few calls and verified the speed (1.5mps) so it seems to be working. I'll be traveling out of state tomorrow night probably to the same area where it broke before. Will report back on the results.

[belmont007]

Let`s see what we`ve got here.:

1) Seems it happens when you travel to a different 3G network
2) Seems it happens with different ROM versions (1.27.12.11, 1.27.12.32 ..)
3) May depends on SIM cards ( old 2G sim for 3G or a new UMTS- USIM)
4) May depends on the Mobile operator. (Problem with T-Mobile, O2...)
5) Does it happen ONLY on unbranded HTC Kaisers or has it ever happened to Kaiser type mobile that was bought in the shop of the mobile operator?? (key question)


no real software solution ?:

Sorry to say but HARD RESET and skipping connection wizard DO NOT solve the problem on all device. I have tested it yesterday, no luck.

Still need more tests... HTC factory should wake-up out there in Asia...

2) You mean different Radio Versions :-)
3) I have a new USIM
4) I use the german E-Plus Network, but tried T-Mobile and Vodafone too -same Problem
5) my Kaiser is unbranded

Hard Resets and skipping the wizard doesnt work for me!

The Telephone-Support of HTC told me that they know the problem and i have to send it to their Service.

I am still waiting, today one week is over!

JoBi

[Brevi]

1) Happens to me anywhere I go (no 3g calls/data unstable/2g works)
2) Diffrent Radio Rom does not change the situation
3) Have (according to O2) the newest Sim card
4) Tried with Vodafone germany Sim - no problems!
However I did not use Data with the Vodafone Sim, because it's very expensive.
5) I have an unbranded HTC Tytn II. But have exactly the same problem with my Hermes.

No difference when doing hard-reset and skipping conn wizard.

I still haven't managed to do the test calls O2 asked me to do..will do so this afternoon.

I read somewhere, that an UMTS handset, when making a call, starts with the lowest possible transmission power and works it's way up until able to send the call. (To minimize SAR)
GSM works the other way around. Maybe the problem is connected to that? On dutty's v3 there is a program called "field test" which might help analyze what the phone does, but I have no idea what the readings mean. :-)

Hi!
Guess what, the problem automagically fixed itself.
I switched to 3g about an hour ago and everything works fine again.
So I guess, this definately was a network issue with my device.

I will post imediately, if the situation changes.
If I can run any tests for you guys, please let me know!!

My Rom, at this time, is Dutty's v3 and Radio 1.27.12.11.
Device is HTC Tytn II (unbranded) 090807(RB01)/EU

I guess after all, scrificing a goat to the god of mobile devices was a good idea! ;-)

Good Luck!

Brevi

[belmont007]

ooh, my friend what a lucky man you are :) I'm just hoping the T-mobile will be as smart as your operator. Anyway, please let us know if anything changes!

[richied]

Brevi,

heres to hoping it stays working..there is definitely something going on with network compatibility on some phones that they aren't admitting to. I read in the AT&t forums of people with Nokia's having similar problems...but it doesn't seem to be really wide spread otherwise there be 3Gclassaction.org web site some place by now:-). I didn't go out of state tonight so no update on my end, but even edge seems to work faster on the replacement tilt.

good luck!

Hi! After a couple of hours of usage, here is my report:
3G calling is 95% working, which is pretty normal for my experience with the network of O2 Germany. However, I noticed that incoming SMS sometimes would come in about 30 Minutes after they have been sent. Also the 3G data connection is not as stable as before and sometimes won't even connect. Very annoing when using ICQ.
I hope this is caused by O2 technichians struggling with base-station software upgrades or something like that and not by my Kaiser.
I talked to an O2 technician on the phone the other day and he was surprised, about the high amount of error reports in their system.
Guess I will send my beloved Kaiser in anyway, if the problems will continue next week.
BTW: I will open a thread concerning the combination of Kaiser and O2 Multicards.

Have a nice weekend everybody!

Before sending my Kaiser back to the factory I am gonna check different simcards from other mobile operators and if there is at least one which works on 3G properly I leave it in. Sorry T-mobile !!!! In such cases all subscribers should say this to the mobile companies to WAKE-UP and do something for it. I pay for a service which they do not provide.

Thats what i have done before i sent it to the Support:

Normally i use my E-Plus SIM but to check out i tried

T-Mobile and
Vodafone

in GERMANY on exactly the same positions like with my E-Plus SIM and.....

SAME PROBLEM :-((



JoBi

[belmont007]

I have just finished the tests with Hungarian Vodafone and T-mobile sim cards and the result is disappointing.

No calls/data/ at all. Both fails on 3G/HSDPA.
However 2G is Okay.
Seems It doesn`t matter what type of sim or mobile operator you use.

Now some of you have already sent the mobile back to repair. I will wait for you guys until it arrives and if 3G works fine I do the same.

Would be good to know how HTC repair them...software or maybe a hardware issue...

[JoBi]

...thanks for your Tests


I will report as soon as i get my beloved Kaiser back from Support.

Hi Brevi and 3G bug infected guys,

Don't know if this helps but here is my story:

- Got my Tilt still locked to ATT -
- Ulocked it by using ATT code (by Ebay)
- got SIM form FIDO network in Toronto -

ROM flashing:
- Couldn't ger hardspl (white screen), instead got SPL: 1.0 OliPof from here:
http://forum.xda-developers.com/showthread.php?t=354061

- My first ROM was - Dutty v3, I like his ROM
- Don't know exactly - if immediately \ or much later - 3G stopped
- Now I got full 3g bars but no data/ dialing
- I've tried all possible RADIOs and ROMs and manual/auto settings,
- Took it with me all over Ontario (province in Canada, I travel a lot) to check areas - no 3G everywhere,
- Fido people have no idea what I am talking about .. :eek:

Don't know if any of above matches your problem, hope that we can find similarity to debug the problem

[peterkiser]

OK guys,
I tried 2 different SIMs on my unlocked Tilt. I tried Canadian Rogers and Fido SIM cards, both networks are actually Rogers (they married) Both SIM cards performed the same - 2G OK, 3G nothing. I found this : http://www.pocketpcaddict.com/forums/front-page-content/21175-rogers-having-problem-3g.html
Don't know what to think about this yet..

Good Morning from Germany,

i just have spoken with the responsible Technican from Company Brightpoint and asked for my beloved Kaiser and he directly answered me, that he will change the mainboard directly and send the Kaiser back today :-)

That UMTS-Problem is well known there!!!


Happy Greetings ;-)

JoBi

[belmont007]

so it is a hardware issue or at least that`s the quickest way to get it working properly. I wonder how many fellows are still suffering of this out there.

In fact, it was not a good point for HTC as all the big telcos are selling this type all over the world.

Let us know when you have tested on 3G and with some travel. Thanks for keeping us posted.

[lthown]

I was having this issue with my At&T tilt - got it replaced under the 1 year warranty (next day shipping of the new handset was $15) and it's been peachy ever since.

Almost to the "T" my story.
I was running Dutty's roms, 6, 7b, v.2, all on Radio 1.27.12.11. I then flashed a new radio for Dutty's v.4. I've been flashing and reflashing roms and radios ever since just looking to get 3G to connect and actually place a call. 2G works great: data, voice. With 3G: nothing.

Surely we don't need to run home to momma (ATT).

What radio were you using and when did you notice the change. What radios have you run?
I've flashed .09, .11, .17, .12.32, and .15.32
Anybody out there make sense of this?

*UPDATE*Talked to ATT. They decided that it was hardware issue and warranty replaceable. I reloaded original rom and sspl per kaiser wiki. Everything went off without a hook. ATT send me a new handset in less than 24 hours. I've got the new one up and running now. Really not much of a hassle. I would advise reloaded OEM rom and SPL or they will consider the phone out of warranty.

[Brevi]

Funny, It happend to me also after flashing a new Rom. In my case from Dutty's 7b to v3. I always thought this was a coincidence, but maybe not. I think I will definately send my phone in, as it's still acting funny sometimes. It's only in a certain cell and only on O2 Germany, but I got some Wifi and now sometimes also GPS trouble.
I will be stuck with my old Hermes for a week then. Oh how I hate that old piece of junk now, that I had a taste of the Kaiser :D

JoBi, did you already get your Kaiser back from Brightpoint?

Greetings from Germany!!

Good Evening to all,

i am very sorry, but i am still waiting for my Kaiser, tomorrow he should be here after 2 weeks and the Technican promised me to send it back with a new Mainboard on Tuesday afternoon.

I will report directly! Have a nice Time!

JoBi

[peterkiser]

mikebraeuer and brevi: SOME MORE POINTS TO THINK ABOUT
1 RADIOS
Currently I have 14.09 with nice clean rom. But I tried them all, sometimes lost GPS, sometimes lost sound - bumpy ride with Herr Kaiser... But never got 3G back.
So maybe this is not related to radios.
2 NETWORK
I don't think it is related to network, as it doesn't dial immediately. If that was a network problem it would first start searching for network before dialing. It sees the 3G (full bars) but all I get when dialing, is some crippled little beep and "call ended" , and of course no DATA
I tried SIMS from two different networks – same problem
When back to GSM only - - no problem


3 BAND SWITCHING
There could be a problem between 2G and 3G switching. Systems like this always start on fastest network and work their way down looking for any signals.
On my ROM I have something called: Field Test (utility of some sort) it actually reads behavior of your 2G and 3G, but I don't really know how to read it yet. However all readings on GSM are ok (I think) but on WCDMA it shows: RRCStatus: disconnected..

4 ROM
Could be hidden setups in ROM that are still related either to tilt or Kaiser or network or something - the hidden setups could be incompatible with your hardware/firmware

Did you guys (flashers...;) ) try to contact Dutty and ask him if he can share some wisdom?? I sent him a note but didn't get back yet. The guy is busy I suppose..

[belmont007]

Reading these new posts I see everyone has the same problem, 100% the same behavior of the phone and the questions are similar.

I am so much into this bug and really waiting for the root cause to be spread over here.
Hmmm, it would be good to get a HTC support guy to let us know what the problem is as all Europe and Americas are infected.

Noone likes having a 3G time bomb embedded in the phone..

[richied]

I just wanted to update everyone that I traveled out of state the other day to the same area where my first tilt started having 3G problems. The replacement Tilt worked fine, full voice, data and 3G with a cooked Rom, dutty's v4 rtm. So, it seems it is a hardware issue of some sort. Data connectivity is sporadic at my home location, but I am pretty sure this is localized to the cell site here...it is only edge and not 3G. This makes debug and experimentation difficult.

rich

[peterkiser]

I am more and more convinced that this could be the hardware, however what is causing the 3G to go bad so quickly??? Is it just a bad series or what? Can this happen again? Maybe HTC people have an answer.

I hate to send the phone back, but guess will have to.
Good luck all 3g sick puppies ...

[JoBi]

Good Evening to all,


my beloved Kaiser came back today and they changed the Mainboard and what i can say til now from at home:

I am reachable at home again :-)
I will test it tomorrow at work and report tomorrow!


I got the Kaiser back with exactly the same ROM and Radio-Version!

Greetz,

JoBi

[JoBi]

As I told you my in my last post, my beloved Kaiser came back from the Support with another Mainboard and my 3G/UMTS is better. I have tested it now from at home and in my office the last two days!

I´ll keep an eye on it because the problem occurs in the past not directly but after nearly 2 weeks of using the phone.


Have a nice day!


JoBi

[peterkiser]

Thanks JoBi for keeping us posted.
You're lucky one, as I can't be without the phone even for the day. But eventually I will have to send it.

Interesting the data is quite OK on the Edge (but not fast enough).
However I need 3G, that is the reason I got this phone in the first place.


I will send it directly to HTC usa (altough it is a Tilt) they will still take a look at it. Don't know if they will charge me as it was flashed so many times...

Hi PK... I have exactly the same problem with a Tilt I bought from eBay, but won't work here on Rogers AT&T. Do you have a name you're sending you're unit to? (e.g. someone who knows about the symptoms already?)

Thanks.

[millercentral]

Thought I'd share my experience. I too recently had a problem that started with a "Red Light of Death". With enough swapping of batteries I was able to get the device started again, but when I did I found it would no longer successufully connect to the 3G network (but GSM/Edge was fine). Uh Oh.

After going through every software solution I could think of, I flashed back to factory settings and submitted for RMA. I ended up having a conversation with a HTC hardware engineer who told me the 3G radio on the returned device had been fried, which was the reason the RedLight was on in the first place (he was at a loss as to why I was able to get it to boot again at all).

In my case at least, the only way to fix it was via RMA, as the hardware itself had failed.

[peterkiser]

Hi Guys,

My Titlt actual works perfect, except on 3G of course. I did swap some Rogers/Fido SIMs today to make sure I am not doing something stupid.

The guy in a local (not Fido or Rogers) but 3rd party dealer saw something like that already. I will send it soon. I will put Tilt ROM.

Question to
millercentral: How long did it take to fix it? Did you pay to fix it?

Answer about contacts:
Talk directly to RMA dep in states, all they need is SN to see if it is still under warranty. 317 818 6981 or tech supp. (ask to transfer you to RMA): 888 354 2375. I don't have names , sometimes it is better just to play it simple:
"I have your product, 3G doesn't work - pls fix it"

Hope this helps.
Good luck,
PK

Question to

Just over 2 weeks. I didn't have to pay as it was under warrenty.

[drtolson]

:) Have to place kudos where they are due... HTC has been very good about accepting back my unlocked TILT from Canada! via RMA. They got it last Friday and yesterday (Tuesday) phoned back to say they were shipping it out, back to me. No mention of cost for repair (and they are SUPPOSED to call first for confirmation!), so I'm hoping that in a couple of days, I'll have a new or repaired TILT in my hot little hands!

For me, it's been one of the most pleasant customer service interactions I've had.

[Am4zing]

Same problem in France with Bouygues Telecom, i didn't use the 3G at the begining but my phone settings was in "Auto" (band), and 3 month after my purchase the 3G issue happened ! i turned my settings into GSM and i thought it was fixed and normal. But i changed my abbo to an SFR (vodafone) abbo and it's now that i discover the real issue, tomorow I call Sirma (HTC support) in order to send the device!

I think that the hardware issue can happened at any time wherever we are !
I did so many hard reset, i didnt use the setting wizard but the issue is still working :(

thank you for your explanations and sorry for my bad english level.

[Ne_RAY]

I had same problem with all roms which I tested but then a changed rom to WM 6.1 a radio rom which I have now and all is working now prerfect and I am perfect using HSPDA and downloading data with 600kb/s speed

But didn't you lose your warranty when you changed your Rom ?

[Qman82]

Hi I came to this forum while looking for that TYTN2 3G issue.
I have the same issues as the rest of u.
I got Radio: 1.27.12.32 and 3G is now not working at all anymore!!!

I work at a Mobile Operator in Belgium and I have sent my tytn2 already to HTC repair. They sent it back after a week with : NO ISSUES FOUND.
I have mentioned the correct issues I had : 3g not working, 2g working and so on...

My colleagues with french ROM and radio 1.27.12.17 seem not to have any issues.
But I see this thread is quiet now.
What did you guys do ??? All have sent it back ? Or you flashed to .17 or ...?
Anyone has a good link to a doc, how to flash radio version or so ?

Thanks a lot !!!

[spengbab]

Same problem here on T-Mobile UK.

ROM Version : DualTouch v6 WWE
Radio Version : 1.64.08.21

I was using HSDPA fine for about 4/5 hours, then it suddenly stopped. Ever since I've had to keep the phone on GSM mode, if 3G is on I can't make calls or anything.

I've tried changing roms back to standard T-Mobile, changing the radio roms and it just wont work. I did hit a bit of luck after going back to the standard T-Mobile rom where HSDPA was working perfectly for about 1-2 minutes then it stopped working again.

[jonc]

I've been having similar issues since switching to using some of the niki ROMs.

It's intermittent problems, sometimes the phone appears to be disconnected, but placing a call to voicemail makes it connect again. Other times (like yesterday) everything appears hunky dory, but calls/texts don't make it through to the phone.

Think I'll probably switch back to one of the Polaris/6.1 radios. I shall let you know how I get on!

[drtolson]

Hi guys... In my case, it was definitely a hardware issue, as after returning from HTC, the unit has worked perfectly on 3G and H. I don't think this is a 'flashed radio' problem, but I'm using the 1.58.21.23 version, since it gives me the best GPS reception/locking here on the west coast of Canada.

Spengbab, Qman84 and Am4zing -- I would definitely contact HTC (or your vendor) and get an RMA to return the unit for servicing. Include a note that clearly defines the problem as the phone will not make calls in 3G mode. That's what worked for me.

Here in NA, I contacted HTC's AT&T help line, got the RMA, sent in the unit with the note and got it back in about a week. They didn't charge me for the repair, but they did charge me for shipping it back.

I think they changed the motherboard in the unit, since my TomTom now doesn't recognize the device.

But I'll try to send my tytn2 back again...
The problem is that I already have sent it once with complete error description.
They have sent it back with feedback = No issues found !! :mad:
So I don't know what more to put into error description.:(

But ok ,tomorrow I'll send it up again via my Network operator company where I work. I hope HTC will fix it and/or replace the necessary stuff.

I'll keep you posted.
Thanx !!

(like that I don't need to reflash it back to original settings for warranty issues)

[infernix]

well, after spending all night flashing roms and radios, I find this little thread. Wish I found it earlier, then i could have slept more :(

My WWE Tytn 2 is from October 2007 and I've been using it with HSDPA since day one here with T-Mobile NL. Worked perfectly up until a day or two ago. Exact same symptoms as described in the thread. Very, very annoying. I guess I'll RMA it too then, with a hardcopy of this entire thread as proof.

The stupid thing is that I don't see how it can *sometimes* work for a few minutes after a soft reset if the hardware is fried. That makes no sense to me. In any case, it's broken :|

[TyTN X]

Same problem here on T-Mobile UK.

ROM Version : DualTouch v6 WWE
Radio Version : 1.64.08.21

I was using HSDPA fine for about 4/5 hours, then it suddenly stopped. Ever since I've had to keep the phone on GSM mode, if 3G is on I can't make calls or anything.

I've tried changing roms back to standard T-Mobile, changing the radio roms and it just wont work. I did hit a bit of luck after going back to the standard T-Mobile rom where HSDPA was working perfectly for about 1-2 minutes then it stopped working again.
I have the latest Dutty rom installed, I am having the same problem as you have! Any solutions??

[infernix]

So I called with tech suppport and they didn't really know what was wrong, so it's being escalated. I'll keep this thread updated when I hear more, hopefully within a week or two.

[jvloyola]

Hello same thing is happening to me here in Mexico, everything was working fine and now if I set the radio to GSM I get voice and data, but if I set the radio to 3G I ONLY get data and no voice.

I've been reflashing for the last three days without any luck.

Please help, somebody help!

Vinny

[infernix]

Wel, totally weird but it started working again today. What I did is I kept the phone on GSM only mode for a while and overnight it seems that the problem went away. I'm still puzzled and will try to reproduce it :)

What I did do is change kaisertweak so it doesn't disconnect after X minutes and kept hsdpa running for a few hours just to see if it would break again (it didn't); not sure if that helps

[Qman82]

I'm afraid the issues will come back. In the beginning for me it also seamed that sometimes it was solved. So my first guess was a network issue. But than it kept comming back , untill it stayed like that.
Now my TYTN2 is still sent to HTC repair , already a week.
I'm curious if it will be fixed now ( second time I send it )

grtzz

[Ronnymes]

Sorry to say but youre problem cant be solved, just got mine back from HTC ( EuroTwice )and they say I have no hardware problems.
Phoned to HTC and they say they know about the problem but cant do annything at this moment...
You can try to switch the simcard.

Edit: new simcard dousn't do the trick, just send a mail to Eurotwice if they want to change the motherboard ( new chip )

[benshan]

Been reading this thread after spending many hours trying to diagnose the problem of not being able to make calls while on 3G / HSDPA mode. Like others, the problem just started one day for no reason. I thought it might have needed a softreset - no help, then hard reset - no help. Then softwares ... no help... I've tried everything and the only temporary fix appears to be to force the phone into GSM mode but ofcourse this means you can't get 3G or HSDPA. So I've sent my phone off to the repair centre with a note about the issue. They say the turn around is five days which I'm pretty happy with. Keep my fingers crossed to get it back late next week and see if the problem has been fixed. I'm in London but I bought my phone off the production line from HK when they first came out. Love my TYTN II. Thanks for the posts people. Good luck to all in getting the issues resolved.

[californiarailroader]

I had the same problem late last month, and even reloading the stock AT&T ROM didn't fix it. After giving me a new SIM and trying to send some settings to my Tilt, they finally agreed it was a hardware defect, and sent me a new Tilt out (Warranty Exchange), all is well again :)

[vacsed]

I have the same problem with my Tytn II which I bought back in October 2007.

I never managed to get 3G working eventhough the 3G icon is displayed on my phone. As soon as I try to make a data connection, the Tytn loses any network signal and needs to reconnect to the network.

This has been the case with any of the first radio ROMs till the latest WM6.1 radio ROMs.

I'm sick of it, as much as I want to like HTC, I only had troubles with them. My first Tytn had the well-known touchsceen decalibration problem, got it exchanged and the new Tytn still had the same problem, although slightly less.

Now my Tytn II never was able to make any 3G connection and offers sub par video as also no 3D hardware acceleration support at all.

I will try to get my Tytn II repaired after 7 months of usage (I waited that long because I always believed that a new radio ROM would fix the problem). If I don't get any satisfactory result from HTC this time, I'm gone for good. No more HTC for me.

[vacsed]

I finally got my broken Tytn II changed. The new one, eventhough it includes exactly the same old OS build and radio ROM as my first Tytn II bought six months ago, detects and connects without any problems to any 3G/UMTS/HSDPA network and internet connectivity works flawlessly.

So this 3G/UMTS issue is definitely a hardware issue and no software patch can fix it. Too bad the two devices I bought from HTC till now all had a hardware issue which slipped through QA (calibration issue on my Tytn I and now the 3G defect on my Tytn II).

[grungysquash]

This thread is interesting this issue has really annoyed me also, the phone is running Dittys WM6.1 WWE and radio ROM 1.58.16.27.

Live in Ausi running Telstra 3G network - when setting the radio to auto on the 3G network the phone just won't work - or should I say it won't make up it's mind if it should work yet with the HSPA activated and running GSM it will run like a charm will no problems at all. switches between Edge, GSM and HSPA without any issues

This problem was evident when I first had the phone but after trying all the roms I have simply given up - never make a 3G video call and never hook into laptop for internet access.

Still if there is a fix for this it would be great.

[vacsed]

Still if there is a fix for this it would be great.

There will be NO fix. Several shipments of Tytn IIs have faulty hardware and no software update will be able to fix it.

I waited 6 months in vain for a fix and finally decided to make use out of my warranty and got a new one which works flawlessly.

If you ever desire to have 3G/UMTS connectivity on your Tytn II you need to get it repaired or replaced... there is no other way.

[Qman82]

I've posted already 2 or 3 messages here,
now I received my HTC TYTN 2 back from repair ( Eurotwice company in Belgium).
It was the 2nd time I 've sent my tytn2 there, first time they said : No issues found :confused:
Now they swapped my gsm , but with a used tytn2..:mad:
Instead of AZERTY keyboard,I have QWERTY now, there are some scratches on it, no screenprotector anymore,
but 3G works, for the moment !
(other radio version on it )...

I waited 6 months in vain for a fix and finally decided to make use out of my warranty and got a new one which works flawlessly.

If you ever desire to have 3G/UMTS connectivity on your Tytn II you need to get it repaired or replaced... there is no other way.

Thanks - will probably so ahead and follow your lead - after all the phone is supposed to run on 3G.

SHAME ON HTC that they have sold so many faulty phones and when it comes to warranty they replace it with and million times used, shitty Kaiser with many scratches !! SHAME ON HTC !!!! :( :(

Hi all,

I've seen a bit of the described behaviour on my phone (MDA compact III; T-Mobile branded).
Unlocked, and flashed dutty's rom.

After 3 weeks bootup in 3g but then after a few seconds connection lost and fallback to gprs.

tried dozens of roms and radio's but no luck. Got myself a Vodafone prepaid card et viola.... 3G / HSDPA. No problems at all lightning fast internet.

Trying to work out with my normal provider (Telfort) what's the problem.

INDEED !!!! Shame on HTC to work with the shittiest Company I know : EUROTWICE in Hasselt Belgium !!!:mad:
I've already sent a mail to them. :mad:

[Junkisbadbaby]

Not sure about the hardware blame as i've had 3 over the last 10 months and the issue has been a pain in the rear for me on all 3 phones (all different roms, varying ages, latest rom 3.28.61.0 WWE, radio 1.65.16.25.

As an aside, tried turning hsdpa off and 6 hours later no problems making or receiving calls, using IE etc. Data speeds okay, but not hsdpa okay....

Anybody else tried this?

BTW, I'm in the uk, using Orange.

Really interesting. I have exactly the same behaviour here in Brazil.

Problem is, I thought that my Kaiser would´t work with my current network (Oi) because it doesn´t have 3G (yet - it should be released in july).

When I turn the phone on, it usually connects as 3G, but the connection falls down to Edge.

Of course I tested it with another network (known to be working with 3G) and the phone flawlessy worked as 3G, so I think I may assume that it it not faulty...

[schizo]

Maybe there are hardware faults, I don't know, for this I cannot give comments. At least from what I and a couple of friends had, it worked well with the 3G networks here. I had test mine with 2 different operators, and both give me 3.5G HSDPA throughput.

The problems I found sometimes due to networks design. Usually the 3G operators (UMTS) start as GSM operator. They had outstanding 2G coverage and capacity since they are working on dual band range (GSM900mhz and GSM/DCS1800mhz). Yet the 3G UMTS part (2100Mhz) is not yet fully deployed in all of their BTS, mostly only on selected cells and hotspots or in urban area.

It happened that when the 3G signal is on lowest threshold level for the phone to switch band to GSM, most of the time the condition makes the handset in ping-pong mode, band-switching back and forth, render it unusable. Nevertheless, I saw this behaviour also happened on my Nokia N70. So I guess this is normal with 3G networks.

I suggest to thoroughly diagonose your problems, first of all you have to make sure you are standing in a good 3G coverage spot. Not in the threshold zone. That way you can 100% sure where is the problem, the networks, or your TyTn.

Hope it helps :)

[mblendinger]

hello, any news about this problem ? somebody found a "fix" or the only alternative is send the device to the support ?

[yana209]

I have the same problem for over a week now. It started all of a sudden, and it's only one month that I bought it. I called HTC customer support and initially the lady asked me to ship it over to them but then she asked if I had upgraded to ROM 6.1? And they think that this upgrade can help me. Well let's see. I'm going to do it now. Will post the results.

Yasir

[mblendinger]

I upgraded to 6.1 standard, and also I test various cooked roms, and then I try like 10 different RADIO roms, (now I have the latest one), but the problem is unresolved.

[yana209]

The upgrade to 6.1 didn't help at all. The problem remained all the same.
In phone settings, I've selected UMTS for network type than auto and ever since my problem is not reappearing. All going good since morning.
Though present setting is like forced 3G so I have to have coverage of 3G to have my phone working, but at least it's working now. So I presume that there's no issue with the hardware. It may be some kind of bug which creates a problem when auto mode is selected and it keeps on switching between 2G and 3G whenever there are signal strength issue or whatever.

I installed many radio's many roms but it just doesn't help to fix the problem. I travel a lot in many countries in Europe, North America and Asia, and connect trough many network providers. Sometimes, and I really don't know why, I can make a connection via 3G. This lasts for a couple of hours and then suddenly its gone again. This convinces me it is not a hardware problem. A silicon chip doesn't repair itself! I can only hope that one of the smart guy's here is able to find a solution. I would be very, very grateful.

A silicon chip can't repair itself, but an FSM can get stuck in an unrecoverable state if something unaccounted for happens. And if that FSM keeps track of its data in flash memory, then things can get quite problematic for a fix.

[mcongosto]

If this is a defect on some devices, shouldn't HTC replace them for free even if they are out of warranty?

I will write to them one this matter.

[olmaster]

Please do this ASAP, I have the same problem on HTC TytnII

[Juang3d]

Can someone try this:

I mena, this procedure to unbrick the kaiser involves erasing all inside the kaiser, if it's some kind of low level software or spl involved hang, then this procedure can unlock this.

Right now i cannot do this because i need my phonebook and my email in the kaiser for my day to day work, but if someone can try please, and tell us if that worked.

Thanks to all.

[drunkbastard]

I've been dealing with the same problem, I would be more than happy to try it except for the same reason - I can't risk losing my Kaiser, it's the only phone I have now. If no one makes the attempt by Nov. 4 (when - theoretically - the Fuze comes out), I will try it. Would love to see if it actually fixes the problem, seems there are quite a few people with the same issue.

[Juang3d]

Great, thanks Drunkbastard, i hope this can fix the problem because in three months i want to sell the kaiser and if the 3G is not working then i must drop the price down :s :)

[olmaster]

Hi
Perhaps someone find a solution ??

[drunkbastard]

First I get the Fuze, then I find a solution or turn my phone into a very stylish paperweight in the process... If the latest and greatest rumors are true, I will be able to start tearing into my Tilt on the 11th.

Same here, had lots of trouble receiving calls, hopefully someone finds out if the problem can be fixed, i loved my tytn but i need to be available for customers.

I did the frankenkaiser because I had a bricked phone (booting into the 3 color bootloader screen everytime).

It did solve the first problem, but didn´t solve the 3G one unfortunately.

Well, then I'm ou of options... must be a hardware issue... thanks, saved me doing it myself and getting frustrated.

[pedrinholcs]

Hi everyone,

Last week I went to Brussels, Neederlands, Germany and Luxembourg and used my TYTN II (Vodafone V1615 bought in uk, with portuguese SIM and manufactory settings) with TOMTOM gps, google maps 3G a H data connection, wifi, car charged the phone with HTC charger and so on...
One day, when turning off TOMTOM and back on I've lost the maps I was currently using (strange, is it any memory fault?!) But then it was all working normaly...

On the airport in Brussels I did a soft reset because I wasn't connecting to the wifi, I got the tricolor SPL screen over and over... After leaving the phone off for a period I was abble to turn it on and it was apparently ok. Used wifi but didn't pay attention to G,3G or H network.

After the plane trip, back in Portugal, I realised that it wasn't signing on to my network (optimus). It got G, then 3G and/or H and after a few seconds it would go out of network...

The rest you know: soft reset + hard reset + rom changed + radio chaged, etc -> No results.

My differences:
- it erased TOMTOM maps;
- got SPL tricolor screen on soft reset
- 3G or H(3G+ since ROM 6.1) icon appears after G and lasts for a few seconds until loses full signal.

I've got no warrenty since I bought it on ebay but I've already contacted HTC...
Anyone without warrenty knows how much will it cost (I don't know if they'll change the board, the 3G antenna...)?

[mister_b]

same problem :-(

god damn htc with their false advertisement :-( "video drivers" +"3G"

[drtolson]

Hi guys... I was one the first to post in this thread, and I guess it's been a while since the beginnings of it.

Just to re-iterate, though, if your Kaiser will work in G or E, but not 3G mode, it's most likely a hardware failure. There were a number of units which came out early on in the release of the Kaiser (especially some of the early TILT models) with 'fried' 3G radios.

I had a TILT model with a dead 3G radio. After reading this thread, I contacted HTC America, with a reference to this thread, who put me through to their AT&T branch, who, after some polite discussion with a tech person, provided me with a Return Merchandise Authorization (RMA). I sent the unit back to Houston, TX (I think it was) and received a repaired unit (new motherboard I think) in about 2 weeks. Only charge was for shipping and customs brokerage across the US/Canada border.

If any of you have a Kaiser which doesn't do 3G, I'd strongly urge you to contact HTC and ask to have it repaired. With some polite conversation, you might even get the repair for free!

I tried the same process in europe with my french TytnII. They couldn't help me for free. The solution is change the motherboard. It costs ~360 euros (~$450).

[yana209]

Hi guys,
I'm coming back to this thread to update you all on the progress regarding the my problematic Kaiser. I had to send it for repairs to HTC and there was no other method that worked (software). I have noticed that they gave me a new piece which indicates that there was some serious problem to the motherboard. 3G so far hasn't shown any problem and everything else as before is working fine.

[diredesire]

I've been having a ton of issues with my Kaiser in 3G mode, once it goes into 3G it will work for ~20 mins, and then it will crap out, and I get the dreaded "beep beep beep" when trying to make outgoing calls. No incoming calls are received during this period.

I had tried several different radio flashes before this, but recently I tried 1.65.29.22, and it helped quite a bit. I was able to use my Kaiser on 3G for much of the day, I checked last night right before bed, and I got the dreaded "beep beep beep" again. I think I will just suffer with edge until I need 3G, and then try to jump over...

I was pretty convinced that my 3G connection was hosed, but we'll see how it continues to work over the next few days..

[GoJets!]

I too am having problems with 3G/UMTS with my Kaiser. Since last weekend, the reception immediately drops to zero once the phone tries to lock onto the 3G network.
I've tried many different ROMs and even more Radio-ROMs, to no avail.
But yesterday I tried the latest AT&T rom from this website from the Kaiser-wiki (the one at the top):
http://wiki.xda-developers.com/index.php?pagename=Kaiser_ROMs

And since then, 3G isn't a problem. Don't know why, to be honest, since I did test the included Radio-ROM seperately last week, with no result.

This might not help everyone, just wanted to share my (temporary) success.

Hello , i expirience very same problem as many others - when 3G is on no incoming or outgoing calls BUT internet working just fine - fast and no problems at all. About people saying is hardwear issue - sorry but is NOT, i try with other provaider SIM and everything work just fine. Do u guys notice how problem occure? "I travel to somewhere and when come back..." Im pretty sure this is some deep level softwear issue - when u are out of your provaider range phone try to connect to other networks and mess up everything. But we need some softwear ninja from HTC to solve this it seems..

[DeepRest]

I've had this problem ever since I sim unlocked my Kaiser. I brought it off my friend who regularily had internet speeds that rivaled my home broadband, now I'd be out surfed by a 56k mdem. I've tried 10's of roms and twice that of radios, including the stock HTC and o2 roms with appropriate radios and SPLs. I am now at a loss, I think the hardware is fine as my friend had no trouble. My current rom (TPC's v11) doesn't even see the HSDPA and 3G signals (although I'll stick with it as I love the moto home) but on other roms that will see it they connect then disconnect after seconds and I can then only get a signal if I go back to a GSM only area (unfortunately for me lucky for everyone else these are few and far between where I live). I'm eager to try bandswitch to force it only to use gsm only as I can see this as being the only way forward I really hope it works because the only alternative I can see is to buy a cheapy phone, I can't go on like this for over another year, and this thread has been going on for 2 years now so I can't see a solution happening soon...

Cheers im4u2nv I'll give it a go although I can't remember if I've tried it or not? I think I was put off because the thread said it was for the Asian market (then again I could be confused).

One question though im4u2nv I see it's wm6.1 my current rom is TPC's v11 with the moto home (which is the first one I really love) Assuming it solves my reception problem do you know if I can use a 6.5 home screen with this rom??? I doubt it but it doesn't hurt to ask.

Unfortunately my phone has now become unuseable.... After a holiday to Cypress I am now totally unable to get any reception at all on my phone despite a hard rest and flashing. This is the last straw, I can only think now it is a hardware fault because I have effectively totally reinstalled the phone os. The phone I have is a bit old to consider an expensive repair.

Like you karaern I am now turning my eye on the iphone, having played with my freinds new 3rd gen i-touch the level of games available on it and as well as other apps has impressed me. Then there is the app store that wm doesn't have.

My contract with o2 isn't up till next spring so i have a while to decide, but I NEED a phone now to replace my knackered kaiser, unless anyone has a suggestion as to how to resurect it???? Please????

[Flying Kiwi]

I NEED a phone now to replace my knackered kaiser, unless anyone has a suggestion as to how to resurect itI recall reading somewhere on this board that some of the very early Kaisers had hardware problems which resulted poor 3G reception (although ordinary old G was fine). The fault necessitated a motherboard replacement as a cure so it'd be worth putting everything back to stock configuration and approaching HTC to see if they can fix it. IF it is caused by this known hardware issue, it may be repaired for free/under warranty.

[kamau]

I see this thread is quite old, so I'll just post what i've seen so far.
I have the same problem as almost everyone here, my kaiser drops network whenever 3g is detected.

Notes.
1. Never travelled, it used to work fine then it slowly started to misbehave and now it won't work in 3g.
2. Cannot recieve phone calls, sms etc whenever 3g is on.
3. Works flawlessly when 2g is on, or I use bandswitch to force it to stay in 2g.
4. Works on other networks just not mine, though the rest only partially support 3g.


What I've tried
1. Stock Rom WM6.0 with different hardspl versions (obviously didn't work)
2. WM6.1 ROM 3.57.50.2 (AT&T Rom found here )
With all versions of hardspl (no joy)
3. WM6.1 ROM 3.34.721.2
hardspl 3.28 (same behaviour)
hardspl 3.29 (didnt work, but took ages to find network)
hardspl 3.07 & 3.56 (not yet tested but doubt it'll work)

My kaiser was bought in dubai and since I don't live there, it obviously cannot be fixed via warranty, it's just over an year old. The stock rom was WM6.0 1.81.

Just posting so i join the rest of the herd as we look up and wait for Neo to come and free us! :(

[kamau]

By the way anyone know the registry key/file/setting that keeps the phone permanently in 2g mode? Basically what bandswitch does?


I can't purchase it so i think I'll just give up and stick to 2g until a fix is available.

TIA
JK.

EDIT: IGNORE ABOVE.
I figured it out, downloaded and installed Schaps CommManager3G, also enabled the band tab and now its permanently in 2g.
You know, I'm on other forums and i keep telling Noobs READ before posting, I guess I should have followed my own advice.
It's all good now, until Neo is freed and we know how to get 3g on the Kaiser working just right.
Thanks for a very helpful site.

Pah, same thing happened to me just now, after 3 years with this phone! Guess they won't be honouring any type of warranty with me...

had one phone for almost 2 years without any problems but then the same prob occurred. mine was still under warranty and I got a new one, not a refurbished one. now after 1,5 month the same problem...

Personally I'm lucky enough to have never had this problem on my one Kaiser that I've owned since they were first released back in Sept/Oct 2007. Replacement hardware often comes with its own warranty - especially if new hardware is provided. Does your provider really only expect their new phone to work properly for 45 days irrespective of whether the original warranty has expired? It's a grey area so make the most of it.

Of course if you've been changing anything at all about your phone away from default, then you should leave things in their original state to make sure this isn't contributing to or causing the problem. Other than some brief trials of WM 6.5 over a couple of days and some WM 6.1 trialling over about 1 month (the longest I could stand without decent GPS), the rest of my TyTN II ownership has been with the ROM/Radio/SPL combination in my signature. I upgraded TomTom from version 6 several months ago.

I have an HTC branded tythII with shipped rom 3.28.405.0 and 1.65.17.56 radio. GPS and GPRS worked fine but had no 3G connection (everytime i chose auto, the network would come and go).

Recently, I visited Konstantinopole/istabul and while there i was using full GPS and I was connected to Turkcell. After my return and as soon as I passed the borders, no service.. nothing.

After trying a few cooked roms (6.1, 6.5 etc, which i had several problems), I decided to flash the latest original HTC(Hong Kong)Rom
ROM version: 3.34.721.2 WWE
ROM date: 10/03/08
Radio Version : 25.83.40.02H_1.70.19.09

Now the phone works but i have no gps signal and in the network settings there is no auto/gsm/wdcma option. So the phone only works in auto mode. The problem appears when the device switches between types of network. When the 3G signal or HSDPA is not strong, the connection is lost until it locks on gsm again, which can take sometime.

As soon as I find the time, I will try some different radios to see if there is any improvment.

Hi guys! I've also 3g problem with my HTC TyTNII. Is there are any solution or this is hardware problem?

[outlogic]

I have the same problem with 3G on my tilt. My cell phone works just fine where 3G is not available. But when it finds 3G, I become unreachable, my calls are interrupted, I can't make a call. Tried the following radios: 1.65.14.06, 1.70.19.09, 1.71.09.01 - but I get the same result

Unfortunately this is a hardware problem. I had the same problem with my phone. I tried everything to fix it. In the end I took a phone that had a broken screen from a friend and replaced the motherboard and now it has been working strong again.

Looks like I have just joined the club of owners of kaisers with fried 3G module.....well it was fun while it lasted more than 3,5 half years.

My htc connects to 3g, take sign, not complete any calls and then drops the signal. I've only rom and radio countless times. It does not work. In another phone sim card works normally.

2G works perfectly.
